Kempton found that groups of EVs could send power to the grid and receive compensation that would help to offset the costs of owning the vehicle. There would be almost no negative effect on battery life or the vehicle’s readiness for use.
Depends on your definition of “negligible” and “ready for use”.
A lithium ion battery cell wears out over time. The more you charge and discharge it, the faster the wear. Look at a ten year old phone or laptop battery for example — it still holds a charge, but not as much.
So if V2G is set to stop feeding when ten or twenty percent of the battery is depleted, I can see that being acceptable. But I don’t know that you’d get much money back from that. Maybe $1 at most. Especially with how stingy private power companies are about compensating power generation like rooftop solar.
Charging and discharging a lithium battery when it’s within the 20% to 80% level adds essentially no wear to the battery. Eg discharging from 40% down to 30% and then recharging it back to 40% basically does nothing to your battery
But I don’t know that you’d get much money back from that. Maybe $1 at most. Especially with how stingy private power companies are about compensating power generation like rooftop solar.
That’s the main problem with the concept, that the incentives and infrastructure isn’t available. I doubt many people would have a problem with minor battery degradation if it had provided them an income stream for 5-10 years. Heck, you could replace the battery and leave the old one to continue feeding the grid.
Actually old electric car batteries are being reused for this purpose already. It’s a major reason why we don’t see more electric vehicle battery recycling, it’s because the majority of them haven’t gotten to the Recycled part of the reduce reuse recycle
That’s what the researchers said

You need a lot more than just the battery pack to charge/discharge the battery.
Yes… You’re covering points that have already been covered in the article. In fact, that’s what the entire article is about…
